X and Y intercepts are part of the basis for solving and graphing liner equations. The X-intercept is the point at which the equations line will cross the X axis, and the Y intercept is the point at which the line crosses the Y axis. Finding both of these points will allow you to locate any point on the line. Identifying X and Y intercepts from a liner equation is a simple process that can be done by anyone with basic algebraic knowledge.

X-intercept

Replace Y with 0. For example, to find the X-intercept of 2x + 5y = 10, you will replace the Y with 0 making it: 2x + 5(0) = 10.
